The runaway pickup became airborne on striking a mid-road plantation about 5.15pm and crashed on top of the second of three minivans, killing everyone inside.
More senior officers were travelling in the third minivan.
The crash came on the road between Surat Thani and Takuapa in Phang Nga, north of Phuket, as the convoy headed back to Bangkok after a trip to Ratchaprapa Dam.
The driver of the pickup survived and faces serious charges.
Rest in Peace. Condolences to their family, friends and colleagues.
